Go for the Holbay
Keep it original
Oh I'm no help am I?
Mine has been a labour of love tho' A hobby to go at when time and money (and kids and Mummy) allow!!
I got a battery from the scappy last week, so I've managed to make lots of electric connections and make things work! I've got lights, reverse lights, wiper motor, overdrive (audible click, then another as I move the gearlever to 1st/2nd gate!),even directional indicators

But the heater blower has blown 5 fuses when I throw the switch to 'fast'
I've also had a radiator re-cored, with a boss welded on so I can put a modern electric switch in for the electric fan I got from the scrappy. (What over heating problem??!!

)
Yep, at this rate you might even see my CAR next year, Ha ha!!
